Etymologically, geometry is made up of two words: geo and metron. Geo means earth and metron is referred as measurement. Geometry is a branch of mathematics which deals with the studies of the problems related to the shape, size and position of figures as well as construction and measurement of angles sides etc. In other words, it is said to be a science which is pertaining to the study of geometrical figures.

Plane geometry is the study of plane geometrical figures. Plane geometry deals with shapes like: circle, angle, triangle, rectangle, square etc. It is a vast study of measurement, construction, area and various applications on plane figures. A solid is a threedimensional surface. A solid figure can not be drawn on a sheet of plane paper because it has thickness as well. Few images of solid figures are demonstrated below:
Solid geometry deals with the study of solid geometrical surfaces. It is concerned with the shapes such as: cube, cuboid, sphere, pyramid, cylinder, cone, prism etc.. Solid geometry is a branch of geometry dealing with the study of construction, measurement of area, volume and many more applications related to solid figures.
Geometry is the study of shapes. Geometrical shapes are generally twodimensional and threedimensional. study of higher dimensional figures also comes under geometry. The list of most commonly studied geometrical shapes is:
 Zerodimensional shape: Point.
 Onedimensional shape: Line segment.
 Twodimensional shapes:
 Circle
 Rectangle
 Square
 Trapezium
 Parallelogram
 Rhombus
 Parabola
 Ellipse etc.
 Threedimensional shapes:
 Sphere
 Hemisphere
 Cube
 Cuboid
 Cylinder
 Cone
 Prism
 Pyramid etc.
 Multidimensional shapes: There are various multidimensional shapes which are generally studied in higher studies and researches.
